Diploma & Master Thesis
The Solar Tower Systems Group of DLR’s Institute of Solar Research has been doing extensive research on Central Receivers to develop cost-effective and commercializable technologies. Thanks to its high heat storage capabilities and durability at elevated temperatures, particle based solar receivers draw attention of many research groups. DLR’s Institute of Solar Research has designed, patented and developed the Centrifugal Solar Receiver (CentRec®), which has experimentally proven capability to provide 965 °C of particle outlet temperature with a 2.5 MWth-prototype (www.dlr.de/centrec).
The focus of this work is to further develop the available experimental test set-up and to conduct experiments with the particle based centrifugal solar receiver. In the CentRec® receiver, the ceramic particles with various diameters (0.3 mm – 1 mm) are moving in an inclined rotating drum, and exposed to concentrated solar radiation. Extensive experimental test campaigns have highlighted improvement potential in the areas of dosing the particle flow as well as accurate measurement of the particle flow.
In the past the team has developed and operated several solutions to measure and regulate particle mass flow. The main objective of this study is to explore improvements of the existing solutions. The innovation of new solutions is encouraged and supported. An experimental test setup is available to be modified to test and validate concepts.
